[PATCH] sata_sis: slave support on SiS965
SiS965 and SiS180 chips must support slave mode, SiS965L and SiS964 chips must not support slave mode. SCR_STATUS for SATA ports in powerdown state fixed. Now returning 0x0113 instead of 0x0117. Avoids problem on detecting sata_sis controller. Signed-off-by: Uwe Koziolek <uwe.koziolek@gmx.net> Signed-off-by: Jeff Garzik <jeff@garzik.org>
